Deep Dive into Reactive Programming with RxJS. In this post, let's cover using Reactive Programming and RxJS when building software applications. We will dive deep into the fundamental parts of working with RxJS. Reactive programming is a way of coding with asynchronous data streams that makes a lot of problems easier to solve.
One of the most challenging aspects of developing any user-facing application is handling asynchronous actions such as user input and API requests cleanly and robustly. Thankfully, over the years, many useful programming paradigms and tools have emerged to help us with that task. One of these paradigms is called Reactive Programming.
In this post, let's cover using Reactive Programming and RxJS when building software applications.
We will dive deep into the fundamental parts of working with RxJS and how it benefits us when building complex applications. You can build on this knowledge further after understanding these basic concepts.
RxJS helps developers author declarative code for handling side effects and asynchronous actions with continuous data streams and subscriptions. Think of a stream as a collection of data that arrives asynchronously over time.
The main building blocks of RxJS include:
1. Observable - An object responsible for handling data streams and notifying observers when new data arrives.
2. Observer - Consumers of data streams emitted by observables. Usually, it's a simple handler function that runs each time a new event occurs.
